JBA 04-08 Ford F-150 4.6L 2V 1-1/2in Primary Raw 409SS Cat4Ward Header

Starting with 3/8" thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built to handle the demands of your 2004-2008 Ford F-150 with the 4.6L 2V engine. They represent a significant step up from the restrictive factory exhaust manifolds, aiming to unlock more power and improve the efficiency of your truck's engine. The primary tubing measures 1-1/2 inches, designed to work well with the stock engine's airflow characteristics.

Constructed from durable 409 stainless steel, these headers are made to endure daily driving, towing, and even the occasional spirited run. JBA's proprietary Firecone collector design is a key feature, utilizing race-proven technology to maximize gains in the RPM range where you'll likely be using your truck most often. The tubing itself is mandrel-bent to maintain consistent diameter throughout, ensuring smooth exhaust flow. You'll also find extra-thick collector domes for added durability.

This header set includes factory-style emission connections, making it easier to integrate with your existing emissions system. High-quality hardware is also included to help ensure a professional, no-leak installation. When you're looking to get more out of your F-150's engine, these headers are a solid option to consider.
